Show ..M RESUMED M' Will Drift Alongside of ! Main Breast to Relieve Water Pressure. I I Work has teen resumed in tie Snake i Creek tnnnel. The heavy water pre-1 pre-1 sure at the breast showing no decrease hoped for by the management, a drift j will be started around to the left of I the present breast. It is planned to I tap the flow of water at a point t'ur-! t'ur-! - ther ahead and thus relieve tho pressure pres-sure at the main breast by diverting the water through the drift. When this is accomplished the work of driving the tunnel ahead at the main breast will i be resumed. i The big bore is now in beyond the I two-mile point. The portal is deliv-; deliv-; ering in the neighborhood of 7500 gal-1 gal-1 Ions of water per minute. A heavy I flow of water was tapped about three I weeks ago. The management, decided 1 that if fhe work, which was becoming I exceedingly difficult, were stopped for a short 'time, the flow of water might decrease aiid thus allow greater progress prog-ress to be made. There has been no apparent decrease in the. pressure, i Once beyond the present breast Gea- l eral Manager George W. Lambourne looks forward to greater progress he-iv he-iv ing made. The new compressor is giv- ing every satisfaction and the company plans to work two shifts with three machines in the breast. The tunnel is to be driven for a distance of 14,000 feet and when completed is to be used 1 for the purposes ot mining and trano-portation. trano-portation. The J. A. Mcllwee Contracting com-' com-' pany is under contract to drive the big : bore ahead. John Matheson, in charge of tho work, expects to make a record before the big bore is completed. It is soven and one-half feet in widtn pnd six and one-half feet in heighth above the rails. Besides this there is a waterway three and one-half feet by four feet, jer, in other words, more than one-halfVof the tunnel is ten feot in hthitt.
